Jacqui Cheng from ars technica took TinEye for a spin and shared her thoughts on our image search engine, saying:

Our opinion of the site transformed from skeptical to impressed as we used it more and more. It’s obviously not meant for casual web browsing or finding out what that crazy animal you saw on the side of the road is. However, if you are trying to keep track of how your creations are used across the web, or you saw an image and want to find out where it came from, TinEye is incredibly useful.

And we are still in beta, building our index and working on some amazing new features that will make your TinEye search experience even better.

TinEye is a reverse image search engine.
You give an image to TinEye to find out where it came from, how it is being
used, if modified versions of the image exist, or to find higher resolution
versions.
